About the store
Experience
I have been teaching math across all levels — upper elementary, middle school, and now Kindergarten in a priority education zone near Paris, France. This broad experience allows me to create resources that fit into a genuine learning progression — not just isolated activities. All my resources are classroom-tested with real students. They are designed to be differentiated, easy to implement, and effective for all levels simultaneously.
Teaching style
My teaching style is built around differentiation and inclusion. I believe every child deserves to participate fully — regardless of their level. But I also believe that good teaching respects the balance between teacher and students. A good resource must be effective for children without overwhelming the teacher. No endless preparation, no complex activities to manage — just simple, clear and powerful tools that allow every child to learn at their own level. Every child plays, every child progresses.
Awards & shining teacher moments
Teaching in a priority education zone is my greatest challenge and my greatest pride. What drives me every day is watching my students grow — seeing them gain confidence, discover the joy of reading, and unlock the logic of mathematics. Every resource I create is born from these real classroom moments. When you use my resources, you are using tools that have already made children's eyes light up. That's my promise to you.
My own education history
I hold a Master's degree in Education (MEEF — Teaching, Education and Training) from the ESPE of Perpignan, France. I then passed the national competitive exam to become a certified primary school teacher in the Paris region. I also completed a University Diploma in Education from the University of Paris, further deepening my knowledge of educational sciences. My scientific background gives me a strong foundation for creating rigorous and progressive math resources.
